The best way to answer this item is to use the Substitution method. Substitute the value of y from the first equation to the y of the second equation such that the second equation becomes,
-4x + 3(x - 4) = -3
Simplifying the equation,
-x = 9
Dividing both sides by -1 gives an answer of,
<em>x = -9</em>
Then, substitute the value of x in the first equation.
y = -9 - 4
<em> y = -13</em>
The answer to this item is letter B.
98-70 is 28 meaning that the range is 28
For this , you use the distance formula
. based on the graph, use points (0,6) and (7,-2), plug them into the formula to get

and you get B, 10.63
